[0035] The working principle of the energy-saving subway lighting device that is easy to hang is as follows:

[0036] Step 1: During the hanging positioning installation, the suspension seat 14 is docked on the top of the subway tunnel, and the expansion bolts are inserted through the position of the installation hole 30 to fix the suspension seat 14 on the top of the subway tunnel. The suspension seat 14 supports the suspension slot frame 1, and then the suspension insertion strip 11 is inserted into the inside of the suspension slot frame 1. The suspension insertion strip 11 is positioned and docked inside the suspension slot frame 1, and the suspension insertion strip 11 is connected to the lighting lamp holder 15, the lighting lamp holder 15 supports the infrared sensor 17, and the lighting lamp holder 15 supports multiple LED lamp heads 16 at the same time.

[0037] Step 2. During precise docking and suspension, the controller 18 pushes the micro-electric cylinder 5, the micro-electric cylinder 5 pushes the push block 4 to move left, the push block 4 drives the sleeve slider 3 to move left, the sleeve slider 3 drives the L-shaped frame plate 6 to move left, the L-shaped frame plate 6 drives the screw 7 to make the sleeve block 9 move left, the sleeve block 9 drives the concave plug block 10 to move left, the concave plug block 10 moves left along the outer wall of the suspension insert 11, so that the pressure sensor 13 is located at the upper surface position of the limit pressure frame 12, and the slide frame 19 is inserted into the interior of the suspension insert 11.

[0038] Step 3: During internal docking, the controller 18 starts the linkage motor 20, which drives the tightening screw 21 to rotate. The tightening screw 21 drives the threaded sleeve 22 to move leftward under the action of the thread transmission force, and the threaded sleeve 22 drives the linkage column 23 to move leftward. The linkage column 23 moves leftward along the inner wall of the slide frame 19. The linkage column 23 causes the displacement motor 24 to move leftward, and the displacement motor 24 drives the rotating rod 25 to move the rotating ring 26 leftward. The rotating ring 26 drives the embedded block 27 to move leftward. The embedded block 27 is inserted into the interior of the hanging insert 11, and the proximity sensor 29 performs distance sensing on the embedded block 27. When the proximity sensor 29 senses, the embedded block 27 docks with the embedded groove 28, and the controller 18 turns off the linkage motor 20. At the same time, the controller 18 starts the displacement motor 24, and the displacement motor 24 drives the rotating rod 25 to rotate ninety degrees clockwise, so that the embedded block 27 enters the interior of the embedded groove 28, completing the internal precise docking operation.

[0039] The screw rod 7 is driven to rotate by the reduction motor 8, and the screw rod 7 drives the sleeve block 9 to move upward under the action of the thread transmission force, and the sleeve block 9 drives the concave plug block 10 to move upward, and the concave plug block 10 drives the limit pressure frame 12 to move upward, and the limit pressure frame 12 is squeezed upward at the bottom end position of the pressure sensor 13.
